Shimano's new Direct Mount Rear Derailleur system gives more space around the rear frame dropout, resulting in easier rear wheel removal. This also allows frame designers to shorten chain stays, increase axle sizes, and move suspension pivots. The Direct Mount system provides a simpler, cleaner look. The Deore XT Shadow+ Dyna-Sys 10-speed rear derailleur delivers reliable and precise shifting with a stiff and lightweight open design. Shadow+ features a super low profile design that reduces the risk of damage from trail side hazards. It also includes a chain stabilising switch that reduces chain bounce in rough terrain, maintaining a more stable drive and shifting. This switch can be turned off to remove the wheel. Direct cable routing prevents snagging from any trail side hazards. The derailleur has an all-alloy construction, leading to lower weight without compromising strength and durability. Four fluorine-coated link pin bushings make this one of the slickest shifting derailleurs on the trails.
